USB input Strange behavior

After loading a basic configuration, we have found that the USB drive is configured as mono on the IP128. The problem is that if we mute the ip128, we always sound on the master !!! .
Conclusion, the unconfigured channel of the USB drive goes directly on the master bus.

The problem was solved by patching the IP in stereo mode.

Strange behavior ! ?

Hi @sno77340,

By default the USB inputs are configured as a stereo input on to a stereo channel.

Can you confirm which template show and scene you recalled and what firmware version you are running on your system?

Best Regards,
